Elastin is a protein found in the skin and tissue of the body. It helps to keep skin flexible but tight, providing a bounce-back reaction if skin is pulled. Elastin tends to deplete as people age, resulting in wrinkled or stretched out skin. It contains the peptides and amino acids of elastin, among them: aspartic acid, hydroxyproline, theorine, serine, glutamic acid, proline, glycine, lysine, and arginine.Moreover, it provides nutritive elements to the skin reinforcing the cutaneous strength that helps reduce wrinkles.
